为什么我的E6300这么差？

我没有超频，以前超到2.8G把主板烧了（华硕P5B），虽然没确定是超频的问题但还是没敢再超。
怎么分这么低啊。
我以前用的是P3 933，现在终于换电脑啦。

还有就是为什么BONIC只用一个核心来计算，任务也只能同时进行一个？

确实有问题。我的是P4 2.8B，基准测试如下：

楼上好NB啊！


我也不知道为什么没有ssse3，cpu-z是可以检测到的，但bonic认不出来

不敢再多超，内存扛不住，主板又不能异步。

分数低会不会和检测不到ssse3有关？

kittyjia

我想对于core 2 duo，BOINC应该有相应的优化。

如果单纯强调cpu主频，LZ不如换成奔腾D 915

超到2.8G分还是不如5楼那位同志。同样的主频，唉。

为什么我整数比楼上的快，浮点却输了呢？是不是和core2duo的架构有关？

我觉得这个可能和你们用的boinc的版本不同有关,还有就算是同一版本,你多测几次结果都不同,我觉得这个没有可比性,还是用linkpack测比较准

kittyjia

双核CPU和单核CPU不可比
